Sort by IP Assignment is not working

[blackthornedk]

NetBox version

v3.0.10

Python version

3.7

Steps to Reproduce

1. Go to IP Address list
2. Click on the heading for 'Assigned', to sort by assignment status

Expected Behavior

The list is sorted, and unassigned IP addresses can be shown on top.

Observed Behavior

En error:

<class 'django.core.exceptions.FieldError'>

Field 'assigned_object' does not generate an automatic reverse relation and therefore cannot be used for reverse querying. If it is a GenericForeignKey, consider adding a GenericRelation.
